2003, Canadian Journal of Zoology (81) 1494-1510
We estimated survival of sea otters (Enhydra lutris) for 1 year post weaning during 1992-1993 in Prince William Sound (PWS), location of the 1989 Exxon Valdez oil spill. We sampled 38 pups in eastern PWS (EPWS), an unoiled area occupied by sea otters for <15 years, and 33 pups from...
A survey of estuarine submerged aquatic vegetation in the northern Gulf coast
J. Carter
2003, National Wetlands Newsletter (25) 9-10, 26
The status of submerged aquatic vegetation along the northern Gulf of Mexico is of concern because of its role in the ecology and economy of the coast. Recent studies by U.S. Geological Survey scientists help assess the factors that contribute to SAV distribution and health....

Physical habitat and its alteration: A common ground for exposure of amphibians to environmental stressors

2003, Book chapter, Amphibian decline: An integrated analysis of multiple stressor effects (Proceedings from the workshop on the global decline of amphibian populations)
Amphibians as a class of vertebrates have persisted for hundreds of millions of years (Stebbins and Cohen 1995), but they are currently threatened by a variety of stressors, many resulting from human-related alterations of the environment. Most species of amphibians live closely associated with moist environments throughout their life and...

Egg-to-fry survival of two strains of Atlantic salmon (Salmo salar) in stream incubators under laboratory conditions
James H. Johnson
2003, Journal of Freshwater Ecology (18) 499-500
Egg-to-fry survival of two strains of Atlantic salmon (Salmo salar) was evaluated under laboratory conditions in two commercial stream egg incubators. The survival was also examined based on egg developmental stage (i.e., green eggs, eyed egggs, advanced eggs). There was no significant difference in survival of eggs in the Jordan-Scotty...

Cibola High Levee Pond Annual Report 2003. Interim Report
G.A. Mueller, J. Carpenter, P.C. Marsh, C.O. Minckley
2003, Report
Bonytail and razorback sucker have once again spawned and produced swim-up larvae in Cibola High Levee Pond (CHLP). CHLP continues to support annual recruitment of bonytail while recent razorback sucker recruitment remains elusive. Thus far, razorbacks have experienced intermittent years of spawning success. Both native species were observed spawning...

2003, Report, Preparing for a changing climate: The potential consequences of climate variability and change (Rocky Mountain/Great Basin regional climate-change assessment)
Three procedures were used to develop a set of plausible scenarios of anthropogenic climate change by the year 2100 that could be posed to the sectors selected for assessment (Fig. 2.2). First, a workshop of climatologists with expertise in western North American climates was convened from September 10-12, 1998 at...
Quantile regression models of animal habitat relationships
Brian S. Cade
2003, Thesis
Typically, all factors that limit an organism are not measured and included in statistical models used to investigate relationships with their environment. If important unmeasured variables interact multiplicatively with the measured variables, the statistical models often will have heterogeneous response distributions with unequal variances. Quantile regression is an approach for...
The usefulness of GPS telemetry to study wolf circadian and social activity
Samuel B. Merrill, L. David Mech
2003, Wildlife Society Bulletin (31) 947-960
This study describes circadian and social movement patterns of 9 wolves and illustrates capabilities and limitations of Global Positioning System (GPS) telemetry for analysis of animal activity patterns. Global Positioning System telemetry was useful in determining when pack members were traveling together or apart and how long a breeding female...
Effects of subcutaneous transmitter implants on behavior, growth, energetics, and survival of common loon chicks
K.P. Kenow, M.W. Meyer, F. Fournier, W. H. Karasov, A. Elfessi, S. Gutreuter
2003, Journal of Field Ornithology (74) 179-186
High rates of Common Loon (Gavia immer) chick mortality have been documented in Wisconsin, especially on acidic lakes, but causes and timing of chick mortality are poorly understood. We modified and evaluated a subcutaneous transmitter implant technique for Common Loon chicks using wild and captive reared chicks. Results indicated that...
Classification of lentic habitat for sea lamprey (Petromyzon marinus) larvae using a remote seabed classification device
Michael F. Fodale, Charles R. Bronte, Roger A. Bergstedt, Douglas W. Cuddy, Jean V. Adams
2003, Journal of Great Lakes Research (29) 190-203
Lentic populations of larval sea lampreys (Petromyzon marinus) are suspected of being a major source of recruitment to parasitic stocks in some areas of the Great Lakes, and methods are needed to estimate habitat and population sizes. A deepwater electroshocker has been used to quantitatively assess larval sea lamprey populations...
Introduction to fire danger rating and remote sensing - Will remote sensing enhance wildland fire danger prediction?

2003, Series in Remote Sensing 4-1
While ‘Fire Danger’ per se cannot be measured, the physical properties of the biotic and abiotic world that relate to fire occurrence and fire behavior can. Today, increasingly sophisticated Remote Sensing methods are being developed to more accurately detect fuel properties such as species composition (fuel...
